Georgetown has allowed ADUs under code amendments adopted in 2016, and it has been rewriting its Unified Development Code, with the new code scheduled to take effect November 1, 2026. City materials on the update describe one ADU per residence, with rules on distance from property lines, parking and utility connections.
What did the 2016 rules say?
According to local reporting, the 2016 amendments defined an ADU as a separate attached or detached unit with a full kitchen and living quarters, allowed rental only on owner-occupied properties, and required three off-street parking spaces. The council removed a proposed 17-foot height cap so the ADU's maximum matched the main house.
Which rules apply to my project?
It depends on when your application is filed and on the final adopted text. The update was still subject to change as it moved through adoption in 2026. We confirm the applicable code with city staff before design and again before submittal.
What else matters in Georgetown?
- The city runs its own electric utility, Georgetown Utility Systems, so service questions go to the city.
- Older neighborhoods near the downtown square include historic areas with design review.
- Newer subdivisions, including large master-planned communities, often have deed restrictions.
- Limestone and slope west of I-35 can change foundation and drainage work.
